Nanostructured Multilayer Coatings for Spatial Filtering
Lina Grineviciute, Ceren Babayigit, Darius Gailevičius +6
Spatial filtering is an important mechanism to improve the spatial quality of laser beams. Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used f…
Inverse design of compact optical cloaks and experimental demonstration at microwave frequencies
Mediha Tutgun, Emre Bor, Mirbek Turduev +1
Inverse design in photonics has gathered increasing attention as a powerful approach that goes beyond the intuition-based designs. In this Letter, we present the inverse design and…
Topological phase transition of the centered rectangular photonic lattice
J. Hajivandi, H. Kurt
A Cm planar photonic material (two-dimensional) including the mirror reflection symmetry is explored where in the Dirac cones appeared at the high-symmetry points of the Brillouin…
Simulating Topological Robustness of Fano Resonance in Rotated Honeycomb Photonic Crystals
J. Hajivandi, E. Kaya, G. Edwards +1
The Fano resonance with a distinctive ultra-sharp, asymmetric line shape and high quality factor Q, is a widely occurring phenomena that has a large variety of optical, plasmonic a…
Topological photonic states and directional emission of the light exiting from the photonic topological structure composed of two dimensional honeycomb photonic crystals with different point group symmetries
J. Hajivandi, H. Kurt
In this work, we investigate a two dimensional honeycomb photonic crystal (2D HPC) with C_6 symmetry point group, which is known to demonstrate a double Dirac cone at k=0 of the Br…
Intensity tuning of the edge states in the imperfect topological waveguides based on the photonic crystals with the C3 point group symmetry
Jamileh Hajivandi, Hasan Pakarzadeh, Hamza Kurt
In this paper, we explore the topological behavior of a two-dimensional honeycomb photonic crystal (PC) based on the presence of double Dirac-cone connected the orbitals p and d, d…
